Product Details

The ADA4691-4 is a quad rail-to-rail output, single-supply amplifier featuring low power, wide bandwidth, and low noise. The ADA4691-4 has two independent shutdown pins, allowing further reduction in supply current. These amplifiers are ideal for a wide variety of applications. Audio preamps, filters, IR/photodiode amplifiers, charge amps, and high impedance sensors all benefit from this combination of performance features. The ADA4692-4 is a quad version without shutdown in a 14-lead TSSOP package.

Applications for these amplifiers include consumer audio personal players with low noise and low distortion that provide enough gain and slew rate response over the audio band at low power. Industrial applications with high impedance sensors, such as pyroelectric sensors and other IR sensors, benefit from the high impedance input, low offset drift, and enough band-width and response for low gain applications.

The ADA4691-4 is specified over the extended industrial temperature range (−40°C to +125°C). The ADA4691-4 is available in a 16-lead LFCSP packages.

Tools & Simulations

Design Tools

Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
